Application lefl Gctober S, 1923. Serial No. 667,341.

This invention relates to phonograph record repeaters, and one object ofthe invention is to provide a repeater' which may be used on variousmakes of talkingmachines,

and in connection with disk records ot various sizes, and which willoperate automatically 'to return the needle to starting position for theplaying ot a record as many times as desired.

A further object of the invention is to provide a record repeater whichis readily and conveniently adjustable for use in connection i with y arecord of any given size between minimum and maximum. j

A stilly urtherobject ot `the invention is to provide a record repeaterwhich is simple of construction, eitieient in operation, and adapted tobe readily applied and adjusted for use, and' which may generallysimulate 20 in appearance a serpent or scroll-shaped body of suitabledesign, thus serving'a's a novelty as well as an article ot utility ofthe character described.

y The invention consists ot' the features of construction, combinationand arrangement of parts, rhereinafter fully described 'and claimed,reference being had to the accompanying drawing, in which :--y

Figure 1 is a plan view of a yphonograph record repeater" embodying 'myinvention.`

. Figures 2, 3, e and 5 are, respectively, sections on the lines 2-2,3;3, 4.--1 and of Figure 1. y

In carrying my invention into practice, I provide a phonograph recordrepeater which, in the form disclosed, comprises ytwo unitary late-likemembers 1 and 2, the member, 1V constituting the main part of the deviceand the member 2 an adjustable needleI guide, as hereinafter described.These members y1 and 2 may he made of sheet metal or other sheetmaterial of requisite thickness, strength and durability, stamped orotherwise fashioned into shape and which may be made plain orunfinished, or finished or ornamented in any desired manner according tothe taste or `fancy of the manufacturer or demand ot the purchasingpublic.l i

` The member 1 consists ot oppositely ex tending arms or portions 3 and1, united at their adjacent ends by a U-shaped or arcu` ately curvedoll'set portion' 5, and thence eX- ribs or rails 19 are arranged tendingin reverse directions on desired lines ot curvature. The armB terminatesat its free end in an inwardly bent or curved head 6, around the innerside `of which is provided an upstanding guide rib 7. Provided forcooperation with this rib is a stop rod Shav-` ing a beveled or taperedinner end 9 and provided at its opposite end with a knob or tlnger piece10. This rod is adjustable to greater' or less degrees beyond the outerend ott the rail 7 in a guide sleeve 11 carried by the head 6 and isprovided with a longitudinal groove 12 receiving a set screw 13 on thesleeve, whereby said rod is held from rotation and whereby it may beiXed in ad- Yjusted position, as will be readily understood.

The arm e* terminates at its free end in a disk or head let, arrangedopposite the head 6, which head 11i is provided with an opening 15 torthe passage of the rotating turntable spndleof the phonograph machine.Provided on said head 14, in alinement with said opening 15, is a clutchheador terrule 16 slotted to provide a series of spring gripping iingers17. These fingers are designed to lgrip the spindle `with sutcientiorceto couple the repeater for rotary movement with the turntable and recordwhen the repeater is not positively held from movement, but have a lightenough grip to slip upon the `spindle to prevent the repeater fromrotating the turntable and record while the composition is being playedandv during which time the reproducerneedle engages the ribs 7 orrodSand holds the repeater from rotation.

Formed integrally with the arm t is asubstantiallyl/shaped or triangularweb 18, the widened outer'edge portion ot' which intersects the arm 4and the narrower or vertex end portion of which extends inwardly inproximity to the odset 5. This part 18 is provided with guide ribsorrails 19 forming the initial portion of a return groove or channeledguideway for the needle. These in close relation and approximatelyparallel at their inner ends along the narrow portion of the part `18,and rflare outwardly vand rearwardly to provide with the web portion 18of the plate a -Haring entranceway 2O to 'said initialportion of theguide groove or guideway.` To

A brace 22 of suitableform-lyingfonthe, opposite side of part 18 from the forward portion ofthe arm 4 may iconnect the head 14 and outer end of arm 4 at a pointopposite'tlieinner end oiferm 4. with the innerend of part' 18, thusmutually bracing andV rein` forcingsaid parts and forming an additionalsupport'to` rest' upon the surfa'ceofthe record desirablyincreasingfthearea ofwthefdevi'ce as a Whole to preventthedevicefronrtilting and adapt the same to restl stably `upontherecord-When"inuseV The- -member'- i2 is arranged J to -liei ibetween thearmsB and 41and isprovided ationeend Withian expanded disk-shapedportion or head-23? arranged i to underlie fthe rupwardly offset,1sulrstantiallly hemispherical'iportion 24 of^a bracket.=plate 25riveted or `otherwise suitably nsecuredito thewoffset 5, said fdisk orhead f 23 being lpivota'lly connected with the part 24by a pinoririfvet126` The arm 2 isi suitably igroovedi and is. provided withspaced` guide railsl 271 `tu i formt a ychanneled guideway iconstituting ftheV .delivery portion of the return groove or :guidewayfrforthe needlegfsaid` delivery portion `and theainitiail portion;herein'betore `aeteired to, f being 1de signed to 'provide a spiral:channeled guide Way lofil suitable spiralrcontoun the-contour of whichmay .be varied` :byadjusting-A the member `2 on i its pivotal:connection 26.\ and in anarc iradiail'lywith:respect to the head 24 and'turntable spindle andacenten of` the record-engagedtherewithl Therails27 are uniformly spacedto provide a eomparatively `narrow `guidewayexcept atitheir inner ends Wherel theyare `slightly spread or flared gto provide an entrance'fportion 28,1deeigned Vto register; with theinner end ofthe initial portion of the guideway in any of therpositions'to which the imembe1m2 maimbewadjusted, ltori' the'icertain guidingLof-t e lneedle from one 'portionuto the other of said guider Way.

As stated., the device in practice may be made of sheet metal or othersuitable material and it may be stamped up to provide stiffening ribs orbosses 3l at proper points to give it any desired strength and rigidity.For the purpose of preventing the device from scratching or otherwisemarring the record, such device may be provided on its underside with alayer or Contact pieces 32 of felt or other suitable material. Thedevice may also be made as plain or ornamental as desired, according tothe taste or fancy of the userpand the demands of the purchasing public.lends itself to a formation which may simulate the general appearance ofa coiled serpent, and it may be enameled or otherwise ornamented todelineate more fully the characteristic appearance of a serpent, thusadapting the device to serve as a novelty as well as an article ofutility of the character described.

While the construction shown is preferred, it is to be understood thatchanges in construction, form, proportions and various details may beresorted to, within the scope of the appended claims, j withoutdeparting from the spirit or sacrificing any of the advantages of theinvention. j
